HENRY MASBRUCH, OF PLATTEVILLE, WISCONSIN.

ATTACHMENT FOR PUMPS.

Application filed March 24, 1925.

T 0 all whom it may concern:

Be it known that I, HENRY MAsBRUoH, a citizen ofthe United States, residing at Platteville, in the county of Grant. and State of \Visconsin, have invented. anew and useful Attachment for Pumps, of which the following is a specification.

The objectof my invention to provide a device which may be readily attached to, and adjusted on, any hand operated pump and which will make it easier to operate the pump; and particularly to provide certain improvements in the means for adjusting the tension in such a device over the structure disclosed in my prior Patent No. 1,503,909.

I attain the objects of my invention by the apparatus illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my invention;

Fig. 2 is a front elevation; and

Fig. 3 is a perspective view of my attachment for pumps detached from the pump.

Like numerals indicate like parts in each of the several views.

Referring to the accompanying drawings, I provide a bifurcated bracket 2 of heavy material adapted to seat on the top of the pump and having integrally formed sockets 15 in which are mounted a pair of posts 14. I provide a clamping yoke encircling the pump below the head thereof and fastened to the pump by the bow 5. Ribs 3 attached to yoke i are adjustably attached to the bracket 2, as shown in Fig. 8.

I also provide arms 6 carried by the yoke 4:, these arms being pivoted with slots 7 in' their ends to receive and engage the chains 8 which are attached to the springs 9, which springs in turn are suspended from eyes 11 adjustably mounted by bolts 10 in any of the several spaced apertures 21 in the bars 12, which bars are pivotally supported at 13 on the posts 14.

I provide depending L-shaped arms 17 detachably suspended from the bifurcated ends of arms 12. L-shaped arms 17 are provided with a plurality of apertures 22, any one of which may be engaged by the bolts 16 by which they are suspended from arms 12. A plate 18 connects the ends of arms 17 and carries a clevis or shackle 19, which is securely fastened around the pump rod 20, as shown in Fig. 1, and may be tightened Serial No. 17,944.

to the desired extent by the nuts mounted onthreaded ends of clevis 19.

The device is mounted on a pump in the manner shown in Figs. 1 and 2. The clevis 19 is secured around the pump rod 20 so that when the pump rod is operated it will operate plate 18, arms 17, and pivotally mounted arms 12v and springs 9, which are anchoredby chains 8 to the stationary arms 6. An improved means for adjusting the device is provided by means of apertures 21 and bolts 10 which permit of positioning the springs. to connect with arms. 12 at any desired point from the extreme ends to points near the posts 14:, thereby varying the tension exerted by the springs 9. The

springs which I prefer to provide may be varied from their full tension of 110 lbs. to a pull of only about 20 lbs. for each spring. The provision of the several apertures 22 in arms 17 also permit of adjustment of these arms and consequently of the point of contact of the clevis 19 with pump rod 20 to suit the device to different makes or sizes of pumps.

What I claim is:

1. In an attachment for pumps, the combination of a bracket, means for attaching the bracket to a pump head, posts on the bracket, pivotally mounted arms on the ends of the posts, the aforesaid arms extending in the same direction and being disposed in a spaced parallel relation to each other, means operatively connecting the ends of the arms with the pump rod to cause the arms to move synchronously with the pump rod, springs adjustably suspended from any one of several apertures in the other ends of the pivoted arms, and means for fastening the lower ends of the springs against upward movement under tension.

2. In an attachment for pumps, the combination of a bracket mounted on the head of a pump, a yoke engaging around the pump, ribs connecting the yoke and the bracket, arms carried by the yoke, said arms having slotted ends, a bow connecting the ends of the yoke, posts mounted on the bracket, arms pivotally mounted on the upper ends of the posts, springs suspended from one end of the respective arms, chains suspended from the other end of the springs, said chains being engageable with the slotted ends of the first mentioned arms carried by the yoke, and means for pivotally connecting the other ends of the pivoted arms to the pump rod.

3. In an attachment for pumps, the combination of a bracket mounted on the head of a pump, a yoke engaging around the pump, ribs connecting the yoke and the bracket, arms carried by the yoke, said arms having slotted ends, a bow connecting the ends of the yoke, posts mounted on the bracket, arms pivotally mounted on the upper ends of the posts, said arms having a plurality of spaced apertures, means for adjustably suspending springs from any of said apertures, springs suspended from said means, chains suspended from the other end of the springs, said chains being engageable with the slotted ends of the first mentioned arms carried by the yoke, and means for operatively connecting the other ends of the pivoted arms to the pump rod.

4. In an attachment for pumps, the combination of a bracket, means for rigidly and adjustably securing the bracket to the pump head, stationary arms carried by and projecting from said means, posts mounted on the bracket, arms pivotally supported on the upper ends of the posts, springs adjustably attached to one end of said arms, means for anchoring the springs on the first mentioned stationary arms, and pump rod engaging means adjustably connected to the other end of the pivotally mounted arms.

5. In an attachment for pumps, the combination of a bracket, means for rigidly and adjustably securing the bracket to the pump head, stationary arms carried by and projecting from said means, posts mounted on the bracket, arms pivotally supported on the upper ends of the posts, springs adjustahly attached to one end of said arms, means for anchoring the springs on the first mentioned stationary arms, and pump rod engaging means connected to the other end of the pivotally mounted arms.

HENRY MASBRUGH.
